The stability of the heater control loop depends on having the correct amount of thermal resistance from oven to ambient (also, on the thermal resistance being distributed similarly to the original scheme).

R-value for commercial aerogel insulation is about double rigid
polyurethane insulation, so half the thickness would be about right.
